Patent DE-4308084-A1 (DE)
Title: Hydraulic control valve
Inventor: DUECKINGHAUS HEINRICH
IPC: F15B13/043
Filed: 1993-03-13
Abstract: The present invention describes a magnetically actuable hydraulic control valve for lowering a cutting unit of a combine harvester, the said cutting unit being raised by means of a hydraulic piston/cylinder unit. The object is to prevent the cutting unit from coming to a stop with a jolt. This means that the cutting unit is first lowered at a high speed and this speed is reduced shortly before the termination of the lowering movement. This is achieved in that the magnet of the hydraulic control valve is first subjected to a high voltage value, thereby making it possible for a large quantity to flow off. Shortly before the termination of the lowering movement of the cutting unit, the magnet is then subjected to a lower voltage value, with the result that the hydraulic control valve is changed over in such a way that only a small quantity of oil can flow off. However, the flow-off of a small quantity of oil at the same time causes a considerably reduced lowering speed of a cutting unit of a combine harvester. It is also possible to lower near the ground at only the low speed.

Title: Method and device for controlling a cutting device for dividing up strand-like continuous material
Inventor: WEBER ROLAND DIPL ING
IPC: B23D36/00
Filed: 1993-03-19
Abstract: In order to divide up continuous strand-like material, a cutting device is accelerated from a starting position at a precalculated time, the starting time being calculated in dependence on the speed of passage, acceleration and the running-up path of the cutting device in such a way that the said device comes into contact with the material at the desired cutting point. In order to prevent drops in speed and tooth flank changeover in the gear of the cutting device (2) when the cutting device (2) comes into contact with the material (1), the starting position (3) of the said device (2) is additionally set in dependence on the speed (vw) of passage and the acceleration (b) in such a way that the cutting device (2) comes into contact with the material (1) at the end of its acceleration phase. <IMAGE>
